Be it known that I, PHILIP MUELLER, a

citizen ofthe United States,"and residing at Decatur, in the county of Maconand State Vof Illinois,have invented new and useful*` 'Improvements in Fuller-Balls,ofwhich the following is a specification.

This invention relates to cocks'orfaucets and particularly to vfuller balls, and has asv i fuller i sleeve 191s externally j threaded fand the opening in g the sleeve throughjwhich the Y stem4 f18`f`passes closely receives "the rstem, there being, however, lsufficient clearancefA l' therebetween to Y permit of I a freeV sliding'rv its objects to provideany improved p ball wherein wear of theV elastic :valvelbfody and strains, tending to crushv this body yor g cause itto assumefabnormal shapes, are re-r duced to a minimum, vso that the useful life of the valve is'materiallyprolonged ;v andto provide afull'er ballwhich is eicient in operation and which is very simple in lconstruction sothat it may" bexmanufactured and placed on theinarket at a llow cost, and` so-that it may be readily assembledgndig.v assembled. 1 1

l'The above and vother objects of my iii-f vention are obtained in the structure 'de-p scribed in theV illustrated in Atheaccompanying drawing, and whereinz# M Figure', 1 is 'a proved fuller `ball-`is applied, y

on fline 2-2 of F ig. 1.

The cylindrical portion 241- of'tlie fer-* Y vrule encircles the valve body 23 and terminates somewhat short fof the valve seat duced portion -18 of thevalvestem-and lois held under limited 'compression so asto yieldinglyy urge the valve forwardly upon.

'In assembling the parts of my improved valve, the elastic valve body 23V is 4first slipped upon the sleeve 19 with its valve seat4V end engaging the flange 21. The ferrule 241 is then screwed -onto ythev threadedendV of Vthe sleeve, the ferrule 251v beingheld against rotation while thev` sleeve Ais benglturned by c Y means of ascrew driver engaging Within theslot22. The assembly is now slipped upon the reducedend 18 of thevalve stem;V the 4spring 28-is slipped upon the inner end of the valve stem and placed under compres'- y sion by the colla-roil washer 27, and-the col#` '1 `lar is heldin place by .inserting the pin 29 in the, transverse holein the stem. The cap 30 is then screwed ontov the nipple 26.

. Inv operation when the handle is .turnedto' Y bring the valve into closed position, the

valve body 23 will engage theseat' 16 and.v upon continuedturningfof the handle, the y stem 15 will move forwardlyof the sleeve v Y 19 andi-thus the spring 28 will be placedun-V der a greater degree of compression.. `The spring thus takes up the greaterportionl of the strain which wouldbeexertedupon the valve body if the springl was notprovidedf u lVhen the handle is turned inia direction to cause a flow of V fluid lthrough'thecoclgthe stem moves rearwardly v and-theshoulder 20 thereof engages the sleeve, Vto move the, sleeve together with the valve bodyf23 `fca1-' `ried thereby from the-valve seat V16.

It will bev seen that my, improved valve j *Y `comprisesa relatively smally number of parts whichmay be easily manufacturedat a small cost. (The parts may be, easily assembled. The valve body is supportedbyfthe-sleeve 19, thefiange21 and the protectingferrule, so that the valve body is not alternately elongated 'and contracted to any great eX- tent when opening and closing thercock. j

Itis obvious thatshould thegcollar21 of the sleeve 19 be omitted andthe'valve body #23 overhang the .forward endl of the sleeve and engage the valvestem, the valve bQdy would tend to bind aboutV the valve ,stem and when the stem lwas reciprocated there greatly increased. y
